Thank you so much David for sharing this.I am on the same architecture. It seems I should spend more time on inserting Multus in GKE and run RTPe in host mode.  Regards,Hossein On Thursday, March 4, 2021, 10:39:12 PM PST, David Villasmil <david.villasmil.work(a)gmail.com> wrote: So here's my rtpengine conf: [rtpengine] interface=internal/[PRIVATE_IP];external/[PRIVATE_IP]![PUBLIC_IP] foreground=true log-stderr=true listen-ng=[PRIVATE_IP]:22222 port-min=23000 port-max=32768 recording-dir=/tmp recording-method=pcap recording-format=eth log-level=6 delete-delay=0 and in Kamailio, you listen on 2 ports, one for the public side, the other for the private: listen=LISTEN_PRIVATE_PROTO:LISTEN_PRIVATE_IF:LISTEN_PRIVATE_PORT advertise ADVERTISE_IP:ADVERTISE_PORT listen=LISTEN_PRIVATE_PROTO:LISTEN_PRIVATE_IF:5080 This is basically my setup, it should be straightforward.

We use both Kamailio and RTPEngine in Kubernetes clusters with Multus CNI to manage both private and public interfaces and we have not encountered any issues so far with this configuration.   Kind regards Julien   De : sr-users <sr-users-bounces(a)lists.kamailio.org> au nom de H Yavari <hyavari(a)rocketmail.com> Répondre à : "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.kamailio.org> Date : mercredi 3 mars 2021 à 20:05 À : "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.kamailio.org> Objet : [SR-Users] Kamailio and Asterisk in K8s   Hi to all,   I am going to run multiple Asterisk instances (Pods) in my Kubernetes cluster. I have a stateless Kamailio sip proxy also. We know that K8s can't handle port range for its services, So we have to use host network for Asterisk deployment. But in this mode, Asterisk pods can't connect to other pods through local IPs and you have to add a second network interface to your pods. One solution is using something like Multus that provides multi-home pods. But it has some issue in host-mode!   Also, Using media proxy like RTPEngine in front of Asterisk instances doesn't make a change. You have to run RTPEngine in the host mode or just run it on a VM with multiple NIC. What is the practical solution for this scenario?   Thank you.   BR Hossein _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
